Backpropagation of some fields is necessary #47
Description
Some selected genes (few, as far as I can tell) have the issue shown in the figure below:
Line 1 and 3 are duplicated, with 3 holding extra information (voltage gating). In this case, for example, the voltage gating information should be back-propagated to the other lines, making 1 and 3 identical (and therefore dropping one of the two).
The issue is harder to fix in columns which are not uniform, like relative_conductance. One cannot simply propagate any value to all other NULL fields, so the solution in this case is more difficult to implement.
It's unclear where these lines come from, but a possible cause would be post-build hook (which have the tendency to create duplicate lines).
